Embodiment 1

[0032]The invention provides a solar photothermal lithium battery that can work in the limit temperature range, and the working principle of the battery at the limit temperature is based on the thermal effect induced by light. The cell can capture solar light through the positive side, and also capture sunlight through the negative side.

[0033] It can be a closed all-solid-state lithium-ion battery or a semi-open lithium-gas-ion battery.

[0034] There are three structural forms of closed lithium-ion batteries:

[0035] S1. From top to bottom, it includes a positive electrode collector, a photothermal positive electrode, an electrolyte, a negative electrode, and a negative electrode collector.

[0036] S2. From top to bottom, it includes a positive electrode collector, a positive electrode, an electrolyte, a negative electrode, and a photothermal negative electrode collector.

[0037] S3. From top to bottom, it includes a positive electrode current collector, a phototherma...

Abstract

The invention relates to a solar photothermal lithium battery that can work in an extreme temperature range, including a closed lithium-ion battery and a semi-open lithium-gas battery. When light is irradiated from the positive side, the photothermal positive electrode can capture sunlight and convert it into heat to increase the internal temperature of the entire battery module, enabling it to work in an extremely low temperature environment; when light is irradiated from the negative side When illuminated, the photothermal anode current collector absorbs sunlight and converts it into heat and transfers it to the electrolyte and anode through the anode, so as to heat the components of the entire battery and make it work in an extremely low temperature environment. The extremely low temperature ambient temperature ≥‑200 o c.

Description

technical field [0001] The invention relates to a solar photothermal lithium battery capable of working in an extreme temperature range and a preparation method thereof, belonging to the technical field of solar photothermal batteries. Background technique [0002] The development of lithium-ion batteries that can work well in cold low temperature environments (~-40°C) and hot high temperature environments (~60°C) is of great significance for energy storage. At the same time, military and medical grade equipment further requires the batteries worn on the back to be able to operate in extreme temperature environments. For example, batteries equipped with space shuttles need to be below -60°C. The battery equipped with the medical sterilization device needs to withstand the high temperature of 120 ℃. Compared with traditional organic liquid batteries, solid-state / all-solid-state lithium-ion batteries not only show great advantages in terms of high energy density, safety and ...
